Please, do NOT force your toddler to hold the pencil the way a school child does, with 3 fingers on the pencil â you may do more harm than good. It is very hard to âunlearnâ a poor pencil grip later in life! Each stage of holding a pencil or crayon is dependent on how âsteadyâ the shoulder and arm muscles are.
In the equation of a straight line (when the equation is written as  y = mx + b ), the slope is the number  m  that is multiplied on the x, and  b  is the y-intercept, where the line crosses the y-axis.
2) Slope -- a flat area that is tilted, not level. Contour lines on a slope are generally straight and parallel to each other. If four people walked away from each other on a slope, one person would go downhil, one would climb, and two would stay at the same elevation. These topographic positions (terrain elements, or topographic features) do not exist in isolation. On the contrary, they tend to occur in more-or-less predictable groups (associations) of related landforms. Two summits, for example, usually are separated by a pass, which in turn serves as the top of two draws.
